problems creating static Qt (was "5.10.1 broke one of my builds")

mzimmers

That makes sense, but it seems that the configure command was ignoring my "-opengl desktop" option when it was part of this command:

    cmd /c "configure.bat -static -debug-and-release -platform win32-g++ -prefix $QtDir `
        -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -qt-freetype -opengl desktop -no-openssl `
        -opensource -confirm-license `
        -make libs -nomake tools -nomake examples -nomake tests"

It was only when I re-ran configure with only the -opengl option, that it appeared to work. But, I just discovered that doing so failed to re-use my -prefix command, so it installed into /usr/local (on a Windows system). So, I'm running it again, using the "-redo" option.

I wonder if the -opengl option is incompatible with one of the other options in that long command line...

SGaist

The options looks correct.

However, what you should do is re-run from a clean state. Changing the OpenGL option is typically something that modifies the build setup.

mzimmers

So, what exactly does it mean to "re-run from a clean slate?" What all do I have to delete or uninstall? The target directory was empty when I did this the first time.

SGaist

It means that if you are using an out of source build, then delete folder in which you called configure. Otherwise, you have to cleanup the sources before calling configure again.

Delete all the files that were not part of the source code package. These are created the moment configure.bat starts running.

Out-of-source builds, as mentioned by @SGaist, are the easiest to clean: You just delete the entire build folder.

If you didn't use an out-of-source build but you did get the code via git, run this from the same folder as configure.bat to preserve your source files but remove all other files:

> git clean -dfx
> git submodule foreach "git clean -dfx"

The target directory was empty when I did this the first time.

The configuration files are created in your build directory, not your target (PREFIX) directory.

P.S. Using -opengl desktop means that your end-user needs OpenGL drivers provided by their graphics card vendor to run apps built with Qt Quick. The drivers provided by Windows itself are too old.

Thanks, JKSH - I need static builds for delivering utility programs to customers. Your last paragraph suggests that opengl desktop probably isn't a good idea for me, then. What is the best approach for producing static builds?

Hi @mzimmers, I'm afraid I don't have much experience with static builds of Qt -- I only use dynamic linking.

Which GUI technologies do your programs use? If it's Qt Widgets or the Graphics View Framework, then the OpenGL setting won't matter because those technologies don't use OpenGL.

mzimmers

I use mainly widgets, so I guess this doesn't matter too much, but I'd like to get to the bottom of the problem.

This is my configure command:

    cmd /c "configure.bat -static -debug-and-release -platform win32-g++ -prefix $QtDir `
        -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -qt-freetype -opengl desktop -no-openssl `
        -opensource -confirm-license `
        -make libs -nomake tools -nomake examples -nomake tests"

Here are some extracts of the output from the static build script. I get the same results when building 5.9.4 or 5.10.1. (These were clean builds; I deleted the source directories and let the script re-extract.)

WARNING: Using OpenGL ES 2.0 on Windows without ANGLE.

Specify -opengl desktop to use regular OpenGL.

Any suggestions?

Thanks...

Do you have the DirectX SDK installed? If not, you should try that to have ANGLE enabled (and hopefully to make away with your problem).

mzimmers

@kshegunov I have no idea, but I'm actually less interested in finding an alternative to -opengl desktop, and more interested in finding out why the -opengl desktop option doesn't "take" unless it's specified by itself (separate configure command). But I'll look into the ANGLE alternative if I can't figure this out.

I'm seeing all kinds of weirdness with this build attempt. My attempts to build on my system drive used up over 260GB of space before failing, so I installed an old HD I had, moved the installer over there, and it built, using only 30GB. As usual, I have absolutely no explanation why this would be the case.

Thanks...

Well, my asking is because ANGLE as far as I know interfaces with the D3D API and should make your build problem go away. Again, I'm speculating, but it's worth a try I think.

mzimmers

@kshegunov the build no longer fails, now that I'm using the 2nd configure command. But I'll look into your suggestion. If it results in a smaller footprint, it's worth doing.

mzimmers

I've come to the conclusion that my original problem stemmed from an odd issue with Powershell. A step in the script invokes an DOS script which in turn invokes the configure.exe program, passing through all arguments it received. At some point, at least one of the arguments "-opengl desktop" is lost. This occurs with Windows PowerShell 5.1 as well as PowerShell Core 6.0.2.

My workaround is to change the script. This area:

    # Configure, compile and install Qt.
    Push-Location $QtSrcDir
    cmd /c "configure.bat -static -debug-and-release -platform win32-g++ -prefix $QtDir `
        -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -qt-freetype -opengl desktop -qt-sql-sqlite -no-openssl `
        -opensource -confirm-license `
        -make libs -nomake tools -nomake examples -nomake tests"
    mingw32-make -k -j4
    mingw32-make -k install
    Pop-Location

Should be changed to:

    # Configure, compile and install Qt.
    Push-Location $QtSrcDir
    cmd /c "configure.bat -static -debug-and-release -platform win32-g++ -prefix $QtDir `
        -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -qt-freetype -opengl desktop -no-openssl `
        -opensource -confirm-license -skip qtwebengine`
        -make libs -nomake tools -nomake examples -nomake tests"
    cmd /c "configure.bat -redo -opengl desktop"
    mingw32-make -k -j4
    mingw32-make -k install
    Pop-Location

Note that I also removed the "-qt-sql-sqlite" option due to other errors. I'd also recommend that you consider changing "-debug-and-release" to "-release."

Thanks to all who looked at this with me.

To me, looking at the most current (1903) version of Windows 10, that you have to sent the whole thing as ONE line to the cmd process. The log I captured showed it only doing the first line (partial command). This caused it to try to do the examples, etc.

Sent it over as ONE long line in the powershell file, and seems to be working better!

But having this all on one is great! Thanks
